CVE-2022-50319: Linux kernel coresight‑trbe removal may trigger warning
CVE-2022-50319 · published 1 year ago
Summary
The Linux kernel component that handles core tracing (coresight‑trbe) can produce a warning when it is unloaded without properly cleaning up its internal state. This does not affect system security but can cause error messages during driver removal. Updating the kernel to the latest version resolves the issue, or ensure the driver is not unloaded on production systems.

coresight: trbe: remove cpuhp instance node before remove cpuhp state
In the Linux kernel, the following vulnerability has been resolved: coresight: trbe: remove cpuhp instance node before remove cpuhp state cpuhp_state_add_instance() and cpuhp_state_remove_instance() should be used in pairs. Or there will lead to the warn on cpuhp_remove_multi_state() since the cpuhp_step list is not empty. The following is the error log with 'rmmod coresight-trbe': Error: Removing state 215 which has instances left.
